Since the early days of the revolution, and since this regime came to power, there has always been one official language, and that was in place even during the previous regime. The official language system, or educational language, has been Persian. But the Iranian Islamic constitution, which in writing is in compliance with many forms and norms, really hasn't been put into action.
In the Iranian constitution there is an article that allows Iranian national, ethnic, and religious minorities to practise their religions and to be educated in their mother tongues. But we've seen otherwise in the last 30 years. It is something totally different. Nothing has been done in that regard. It's there on paper, but since the revolution, the situation of the minorities has always been as it is in regard to their educational rights.
As to whether they're allowed to watch programs, as I said, gladly, with technological advances, especially the advance of satellites, Kurds right now enjoy the freedom to watch maybe 10 or 15 Kurdish satellite stations that have nothing to do with the government. They are actually run outside the borders. It helps a lot, in many ways, that people at least can watch news, programs, and shows in their own language. They not only have a different perspective but can also practise their own language.
So in many ways, it has helped the situation, but the government has also tried to open up, for example, some Kurdish programs that propagate its policies. You know how they do it. But again, it has been there since the revolution, and it continues.
